Amidst a dismal season in Dortmund, Jürgen Klopp, the charismatic manager who brought Borussia Dortmund (BVB) out of the wilderness and back amongst Europe’s elites, announced his plans to step down at the end of the season after seven years at the football club. By resigning, Klopp leaves large looming questions about the club’s future, while setting himself up as the hottest managerial commodity in soccer.
 
When Klopp arrived from Mainz in 2008, Dortmund was far from its past heights. Teetering near bankruptcy in the mid-2000s, the club suffered on the field as a result of player transfers and payroll cuts, finishing seventh, ninth and 13th in the Bundesliga in the three seasons immediately preceding Klopp’s appointment.
 
Klopp brought a charisma and energy to BVB, manifested best by his roster, which was restocked with young talent like Mario Götze, Mats Hummels and Robert Lewandowski, and the team’s counterpressing system, a style not unlike Barcelona’s. After winning back possession though, Klopp’s team serves as sort of the antithesis to the methodical tiki-taka passing of Guardiola’s Barca, setting up lightning quick, direct attacks, that are exhausting but simultaneously exhilarating and beautiful.  
 
For a time, it was also incredibly successful. Dortmund climbed out of mid-table anonymity in 2008 to back-to-back league titles in 2010/11 and 2011/12, including the double of the league and DFB-Pokal, the German equivalent of England’s FA Cup, in 2012. While the team fell short of three consecutive titles, it made it to the Champions League Final in 2013 before falling to bitter rival Bayern Munich.
 
Success comes at a price, though. Bayern pilfered and modified the counterpress to suit its skilled passing game. In its 2013 season, Bayern won three trophies, including the Champions League title, then went on to poach Götze and Lewandowski  from BVB in consecutive years.
 
This season, Dortmund, hampered by injuries, was bottom of the table midway through the campaign. After stringing together recent wins, BVB has climbed to ninth, but will certainly miss out on next year’s Champions League. Thus, the Klopp era at Dortmund ends not with a league title, but a whimper.
 
As a replacement, Dortmund is set to bring in Thomas Tuchel, who, like Klopp, was the manager at Mainz before taking the Dortmund job. Tuchel is regarded as a brilliant tactical mind, and for good reason. At Mainz, his teams have effortlessly switched between formations and different play styles not just from match to match but within matches as well.
 
Perhaps his most successful tactical scheme is the transition from a high press in an attempt to win back possession, to a lower-stacked defensive line, content to sit back and absorb pressure. Switching between the two distinct defensive structures can catch the opposition off guard, and it provides the flexibility necessary to counter different playing styles. Tuchel’s tactical acumen and flexibility alone should breathe fresh air into a squad that has looked stifled at times this season by Klopp’s one-dimensional style.  
 
Klopp’s departure also raises important questions about the future of the roster. Captain Mats Hummels has been heavily linked to Manchester United for a summer move. Marco Reus, for my money one of the most exciting players in the game, has also been heavily rumored to be leaving this summer. With Klopp leaving, it will be interesting to see if Dortmund’s stars follow suit.
 
Already swirling are the potential landing spots for Klopp, who will undoubtedly be linked to every high profile opening, especially in England, where he’s expressed interest in managing next. He’s been mentioned as the frontrunner for the Manchester City job, amidst rumors that Manuel Pellegrini will be sacked after a very disappointing season defending City’s Premier League title. City is in dire need of a retool, with one of the oldest and most expensive squads in England, and Pellegrini is a likely casualty of any rebuild.
 
A more likely destination, should it choose to move on from Brendan Rodgers, is Liverpool. It’s not that Rodgers has been awful—his squad was within a Steven Gerrard slip of the title last year—but his transfers have been questionable, and Liverpool’s top-four chase is quickly losing steam after the team was flattened by Arsenal and United in recent weeks. It’s hard to imagine Liverpool sticking with Rodgers should Klopp express interest in the position.
 
Klopp is a charismatic manager who thrives on emotion. A packed Anfield singing “You’ll Never Walk Alone” seems a much better fit for him than the new money of Manchester City. For that, a job like Liverpool seems a more realistic next step for Klopp.
